| Text Description: | Hand sample; >20g. Reddish-gms dark grey lava from talus derived from cliff to SW and sitting on top of 2008 deposits. Lava forms cliff easily 40 m tall, mostly massive 3-4m wide columns, mostly vertical w/ poorly-developed sub-horizontal parting at ~1 meter intervals. There is one noticeable diagonal parting zone. Was here in mid-late morning as thousands of auklets came on shore. Points of activity are this talus and another large talus, apparently on top of 2008 deposits to southeast - up towards crater rim. Basalt, medium gray with purple cast; obvious phenocrysts rare. Rock largely crystalline w/ microphenocrysts down to 0.25 mm. Overall plag>>cpx. |
